How do I know if my finch is male or female?

Male finches are natural singers. They sing complex, rhythmic songs to attract females and establish territory. If your finch chirps constantly, whistles, or sings melodious notes, it’s most likely a male. Female finches, on the other hand, do not sing much. They might chirp or make simple sounds, but they won’t produce a full song. If you notice beautiful, continuous singing, you have a male finch.
